I was pretty skeptical about this at first, but I ended up buying a few of these and now we use them all over the place, in our refrigerator, in our cars, and in our lunch bags. We have them in the fridge and freezer, and my wife even keeps one in her lunch bag. Somehow, it actually works. Our fridge doesn’t have that mixed-food smell anymore, and even the freezer smells neutral instead of like frozen leftovers.What I like is that there’s nothing to replace, no filters, no refills, and nothing to plug in. You just drop it in and forget about it. It’s also nice not having to worry about baking soda spilling everywhere or getting soggy over time.The downside is definitely the price, and I can’t really explain the science behind how it works for “up to 10 years,” so you kind of just have to trust it. All I can say is that based on our experience, it does reduce odors, and enough that we kept buying more for different spots.If you’re tired of fridge smells and don’t want to deal with boxes of baking soda anymore, this is worth trying at least once. It’s not cheap, but for us, it’s been one of those weird little things that actually lives up to the hype.
